Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve testing, in particular to a hydraulic butterfly valve testing device. Background Art

[0002] Before butterfly valves leave the factory, their air tightness parameters need to be tested, and they can only be sold if they have good performance. At present, most of the detection devices used for butterfly valves have complex structures and cumbersome operations, and must be inspected by professionals, resulting in many testing links and low work efficiency.

[0003] After searching, the application with patent number CN209745481U discloses a hydraulic butterfly valve test bench, in which the upper end of the cabinet is connected to an operating table, and a first hydraulic cylinder is installed on the upper end of the cabinet through a bracket, and the output end of the first hydraulic cylinder passes through the operating table and is connected to the test bench, and exhaust ports are respectively connected to both sides of the test bench, and the upper end of the test bench is connected to a positioning table, and the upper end of the operating table is also connected to a mounting frame. The first hydraulic cylinder drives the test bench and the positioning table upward, so that the upper and lower ends of the butterfly valve can be clamped and sealed at the same time, thereby speeding up the test efficiency.

[0004] However, due to the setting of the positioning table and the external fixing sleeve, the butterfly valve is placed on the positioning table, and then the external fixing sleeve compresses and seals the top of the butterfly valve. The butterfly valves have different sizes, which causes the external fixing sleeve to be easily misaligned with the butterfly valve when it moves toward the butterfly valve, resulting in poor sealing and low positioning efficiency. At the same time, due to the setting of the air inlet and exhaust port, the sealing of the butterfly valve is tested by gas, which is not easy to be seen and detected by the naked eye, resulting in low accuracy and poor effect of the test result.

[0005] Therefore, we proposed a hydraulic butterfly valve test device. Utility Model Content
